Cryptopals challenges solve with Python3

What is Cryptopals?

Cryptopals is a cryptography exercice list covering much of the area content. All about that you can find here: I'm the LINK(not from Zelda C:)

Proposal

The mainly proposal here is just to practice, I'm CTF player that solve crypto challanges and this is just my training C: and of course, knowledge dissemination!

Run

To run, you just need to:

$ python3 SetX/Y.py
